Every aquarium plant has a care profile — light demand, CO2 requirement, growth rate, mature size, and temperament — and buying without reading it is how tanks end up with a high-light carpet melting under a low-light fixture. These profiles give you the numbers that matter before you buy: low/medium/high light needs, whether CO2 is optional or required, growth speed, placement zone, and propagation method, plus the honest difficulty rating and the mistakes each species punishes.
Use profiles comparatively. Choosing a foreground carpet? Compare Hemianthus callitrichoides against Monte Carlo and dwarf hairgrass on CO2 demand and trimming frequency before committing. Want red plants? Check which species actually stay red under your light level — many only color up under high PAR with nitrate limitation. Filling a shrimp tank? Filter for slow-growing epiphytes like anubias, bucephalandra, and java fern that will not outgrow the scape or demand constant pruning.
Each profile also covers identification — telling cryptocoryne species apart, spotting the difference between similar rotala varieties, recognizing emersed vs. submersed growth forms at the shop — so you bring home the plant you actually wanted. Bookmark the profiles for species you own; they double as quick-reference care cards when something looks off.
